Unlike a simple SPL meter or RTA (Real-Time Analyzer), Smaart v9’s primary power lies in its Dual-Channel FFT (Fast Fourier Transform) analyzer. This measures a relationship between two signals: a Reference (input to the system) and a Measurement (output from the system).
The manual stresses that by comparing these two signals, you eliminate the influence of the source material, giving you the true complex response of the device or acoustic space you are testing.

Using the manual’s recommended steps:
On page 78 of the Smaart 9 manual (depending on version), there is a section titled "Coherence Function." It defines coherence as "a frequency-domain estimate of the linear relationship between the reference and measurement signals."
That is math-speak for: How much you can trust this data. smaart 9 manual better
The Better Interpretation:
The manual gives you the definition. This article gives you the action. To use the Smaart 9 manual better, attach a "so what?" to every math definition. Unlike a simple SPL meter or RTA (Real-Time
